How do I add a second Category Box?

I had this done a few years ago on an old site but do not remember how to do it.

I want to add a second category box below the default one. I am setting up a store for my wine shop and want people to be able to search the categories using both the grape names and there country of origin. The items will be copied in the second category box. Thanks in advance.

In the current version of Zen Cart this requires custom programming. You would need to clone the categories sidebox module and its associated sidebox template, or amend the document categories box to restrict each to the categories that you want to display.

However, it is a non-trivial task, and I assume that when you say that you had this done, you mean that you got somebody with programming skills involved. If you don't have these yourself, you may wish to consider the commercial help wanted forum for this change.
